The theme thus far in Doctor Who's eighth season seems to be "deconstructing heroes," most notably the Doctor. The Doctor's questioning whether he's a good man, but also the validity of his battle against evil. It's somewhat grim stuff — until this week's Robin Hood episode, when it turns swashbuckling and hilarious.

Games with isometric graphics—a slightly rotated view with a top-down perspective—were a big deal several years ago. Static, isometric maps, mostly used in strategy and role-playing games, allowed the developers to create spectacular, detailed visuals, and most of them have aged really well.

We all know the scene: It starts when a character in a fantasy story swears an oath. An oath... in blood. He dramatically unsheathes a knife, places it across his palm, and makes a fist before running the blade through his hand.
